Filed: 1964-06-09
Abstract: A composition which is normally fluid but shows a substantial increase in viscosity under the influence of a transient electric field comprises: (a) at least 10% by volume of SiO2 of average particle size 0.04 to 10 microns and having not less than 5 Si-bonded OH groups per square mm  of SiO2 surface area; (b) 0 to 4 molecules of free water per sq. mm  of SiO2 surface area; and (c) a non-polar oleaginous vehicle having a dielectric constant < 5 and which is weakly absorbed by SiO2 (e.g. refined mineral oil).  A minor amount of a neutral fluidizer (e.g. glycerol mono-oleate) may be present. The quantity of particulate SiO2 may be sufficient to provide an average distance of 0.01 to 0.3 microns between SiO2 particles in the composition.  0.5 to 1.5 of Si-bonded OH groups per square mm  may be esterified to OR groups where R is a residue from a polyhydric alcohol or a polyhydroxy ester (e.g. a glycerol mono-oleate residue). The composition may contain a mixture of two different types of SiO2 in a volume ratio of 1:3 to 3:1, one having not less than 7 Si-bonded OH groups per square mm  of surface area and the other containing 4 to 6 Si-bonded OH groups and 0.6 molecules of free water per sq. mm of surface area.  A carboxylic acid having M.W. < 200 may be present at 0.2 to 1.0 molecules per sq. mm  of SiO2 surface area.  The composition may also contain 0.1 to 25% by vol. of a basic N-containing organic compound, e.g. a primary, secondary or tertiary amine, an aminoalcohol, aminoether or diamine.  In this case viscosity changes under the influence of D.C.  From 1 to 40% by weight of a particulate conductive material (e.g. Cu) having average particle size < 30m  may also be present.
